Bengals LG Clint Boling is rehabbing an ankle injury at OTAs, but he's expected to be ready for training camp. Boling, a 2011 fourth-round pick, started all 16 games at left guard last season, and he graded out as Pro Football Focus' No. 10 left guard. He may have to compete with veteran Travelle Wharton for the starting gig this season.
