Indianapolis Colts OT Anthony Castonzo is expected to start at left tackle with OG Jack Mewhort at left guard and C Ryan Kelly in the middle. Two jobs remain up for grabs, as OT Joe Reitz is the incumbent at right tackle, although OT Le’Raven Clark might contend. OG Hugh Thornton (ankle) appears to have a leg up at the right guard spot, but he has missed time in the spring with an ankle injury. OLs Denzelle Good, Jonotthan Harrison and rookie Joe Haeg are also in the mix.
