If injuries were the cause of Andrew Luck's struggles thus far this season, the Indianapolis Colts have reason for optimism heading into the final eight games.
According to a report from NFL Media's Ian Rapoport, Luck, who has battled injuries through much of the first half of the season is "full healthy."

Luck missed two games with a shoulder injury, while Jay Glazer of FOX Sports reported last Sunday the three-time Pro Bowler had been dealing with cracked ribs suffered in the Colts' Week 3 win over the Tennessee Titans.
The 26-year-old Luck has thrown an NFL high-12 interceptions. At 3-5, with both Luck and the team performing well below expectations, the Colts fired offensive coordinator Pep Hamilton on Tuesday, replacing him with Rob Chudzinski.
However, injuries may not be the only answer to what ails Luck. Rapaport notes that the quarterback was also considered completely healthy for the team's 29-26 OT loss to the Carolina Panthers on Monday. Luck once again played poorly in the first half of the game before rallying the Colts and forcing overtime.
Indianapolis hosts the undefeated Denver Broncos on Sunday.
