MCL sprain will sideline Colts left tackle Anthony Castonzo

Fifth-year blocker suffered injury on final series of Sunday win at Atlanta and is considered 'week-to-week.' Cornerback Vontae Davis is 'day-to-day' with a hamstring injury suffered in same game.

Indianapolis Colts offensive left tackle Anthony Castonzo will likely miss Sunday’s home game against Tampa Bay with a medial collateral ligament sprain.

Head coach Chuck Pagano said Monday Castonzo is “week-to-week” with the injury, which forced the lineman to leave Sunday’s 24-21 comeback win at Atlanta. “Week-to-week” typically means a player will be out for at least a week or two if not more, as opposed to when players are regarded as “day-to-day” and possible to suit up on a game day.

Pro Bowl cornerback Vontae Davis was classified as “day-to-day” after leaving the Falcons game with a hamstring injury. His status will continue to be evaluated through the week. The best guess on his availability likely can be determined by how much he practices this week.

Castonzo has not missed a start in his 70-game career since his rookie year in 2011, when he sat out four games. Although he’s struggled at times this season, he’s considered the Colts’ best offensive lineman and was rewarded with a four-year, $43-million contract extension before the regular season began.

When Castonzo was hurt on the final series, the Colts adjusted by shifting right tackle Joe Reitz to his spot, moving left guard Jack Mewhort to right tackle, where he started the first two games of the season, and inserting Lance Louis at left guard.

It’s not like the Colts have many other options other than where to play Reitz and Mewhort. Offensive guard Todd Herremans, signed as a free agent in the offseason, has played tackle in his career but he’s been ineffective and was a healthy inactive against the Falcons.

The Colts (5-5) have won back-to-back games and are tied with Houston atop the AFC South Division entering Sunday's game against the Buccaneers (5-5) at Lucas Oil Stadium.

Pagano said Pro Bowl safety Mike Adams, who missed the Atlanta game with an ankle injury suffered in the previous game two weeks earlier, is also “day-to-day.”

Rookie wide receiver Phillip Dorsett, the team’s first-round draft pick, is expected to return to the practice field this week, Pagano said. Dorsett suffered a lower left leg fracture on Oct. 25 that required surgery. The Colts’ estimated recovery timetable was four to six weeks.

The 29th overall selection has played in seven games as a reserve with 11 receptions for 167 yards and one touchdown.
