Jackson's early return to practice Thursday surprised some because it normally takes players a full year to recover from ACL surgery. Jackson had his surgery Dec. 1.
Jackson says he is not yet 100 percent, but he and Hart are both clearly ahead of schedule. Hart also tore his ACL in October and said he could pretty much do everything -- if asked.
Neither player would say whether they expect to be on the field for the team's first training camp practice Aug. 1 in Terre Haute.
