Miami Dolphins defensive end Derrick Shelby was arrested over the weekend after an incident at a Fort Lauderdale bar and Monday he was suspended indefinitely by the team.

“We are still gathering information,” coach Joe Philbin said, “But I feel like from the information that I have at the present time that I took the appropriate action and suspended him indefinitely.”

Shelby’s arrest was only part of the headline-grabbing news Monday as the Dolphins (2-2) prepare to host Green Bay (3-2).

The other shocker came when Pro Bowl center Mike Pouncey, regarded among the top five in the NFL at his position, seemed to hint he might be moved to guard this week and that guard is his preferred position.

“Guard is my position,” Pouncey said. “I was kind of forced to play center when I got drafted here. Other than that, guard has been my position I played my whole life.”

Pouncey was an All-America guard as a sophomore at Florida in 2009, when the Gators won the national title. He was moved to center in 2010 as a junior. He was selected by the Dolphins with the No. 10 pick in the 2011 draft, the highest a center has ever been selected.

If the Dolphins want to put their best five offensive linemen on the field, regardless of position, shifting Pouncey makes sense.

Under that scenario Miami would likely have Samson Satele at center, Pouncey at right guard, Ja’Wuan James at right tackle, Daryn Colledge at left guard and Branden Albert at left tackle.

That would mean right guards Dallas Thomas, the current starter, and Shelley Smith, the starter until he sustained a knee injury, would both be relegated to reserve duty.

The key is whether Pouncey could acclimate himself to a new position in the span of a few practices.

Miami’s offensive line was a disaster area last season when it allowed a NFL-high 58 sacks and had a rushing game at ranked 26th in the league at 90 yards per game.

The Dolphins opened the season with five new starters and it would have been four if Pouncey wasn’t injured. So far they’ve showed improvement by ranking fifth in rushing at 142.3 yards per game.

Their nine sacks allowed is only tied for 16th best in the league, but it is better than a year ago.

Philbin did not offer any insight into his thinking last week when asked how he might configure his offensive line.

“Nothing is off the table,” Philbin said. “We will see one day at a time and see if we get the best five guys out there, whoever those may be, whatever combination may be. We’re open to anything.”

REPORT CARD AFTER FOUR GAMES

PASSING OFFENSE: C — QB Ryan Tannehill has been inconsistent. So have the wide receivers, tight ends and offensive line. The short and intermediate passing game is developing, but the deep passing game remains non-existent. Inaccurate passes, drops and sacks have all been issues at times. But Miami is spreading the field and creating mismatches as it intended.

RUSHING OFFENSE: B — Surprisingly, Miami started the week fifth in the NFL at 142.3 yards per game. RB Knowshon Moreno has basically missed three games, but Lamar Miller (49 carries, 277 yards, 5.7 yards per carry) has stepped in and saved the day. And the offensive line has been pretty good, too. This might be the biggest shock on the team.

PASS DEFENSE: C-plus — Miami didn’t have an interception until Week Four, but the pass rush has been as good as advertised. The Dolphins’ defensive line is among the best in the NFL and that’s been the force behind the pass defense. Getting S Reshad Jones back in the mix should make the secondary stronger. Buffalo and Kansas City had success passing, and that’s a bit concerning.

RUSH DEFENSE: C-minus — This is still a concern, and that’s disappointing. Poor tackling is the main culprit. Miami began Week Four ranked 14th in rushing defense at 107.3 yards per game. As well as the defensive line has played, as well as the backup linebackers have done, the Dolphins still are not a good run defense.

SPECIAL TEAMS: C-minus — Inconsistency has been a huge problem. Miami has blocked a punt, but it had a punt blocked, allowed a 102-yard kickoff return, missed a field goal and lost two fumbles on punt returns. The Dolphins have had lots of personnel turnover, but part of that is their own fault because of front office decisions. Regardless, this area has to improve if Miami wants to make its first playoff appearance since 2008.

COACHING: C — Play-calling has been good overall. But the coaches just can’t seem to reach these guys. The dropped passes, poor tackling and inconsistent play might not be the coaches’ fault, but it is their responsibility. The Dolphins aren’t among the NFL’s most talented teams, but they have better talent than a year ago when they finished 8-8. And so far it hasn’t showed.
