I don't know if this is yet another sign that Charlie Johnson's injury is worse than we think it is, but the Colts used an open roster spot today to sign tackle James Williams, a rookie from Harvard. Also likely factoring into the signing is the fact that Jacques McClendon has sat out several practices of late, as has Jeff Saturday and Ryan Diem. It's unclear if these absences are injury-related. In Diem's case, his wife just had their first child a few days ago. Diem, like Williams, is a tackle.

The newly signed rookie is a 6'4, 295 pound product of Ivy League Harvard. He signed with the Tampa Bay Buccaneers after going undrafted in the 2010 NFL Draft, but was cut sometime right before or during their camp. 

Since Williams was not invited to the Scouting Combine in 2010, it's tough to get data on things like bench press and 40 times. However, we do know he pretty damn smart. He jilted law school in order to follow his dream of playing in the NFL. Despite playing for an Ivy League school, he did standout.

From Walter Football:

An athletic left tackle, James Williams was one of the main reasons why Harvard had the most potent offense in the Ivy League. He qualified for the conference's first team.

With Charlie Johnson possibly out for Sunday's pre-season game against the 49ers, Williams might get to see some immediate action.
