San Francisco 49ers wide receiver Joshua Morgan clearly looked like he'd suffered a significant injury when he went down in the final minutes against the Tampa Bay Buccaneers. It wasn't clear how bad the injury was at first glance, but early prognosis out of the Niners locker room did not look good. Morgan is already expected to undergo surgery, which probably means he'll be sitting out for a significant period of time.
Today, Niners head coach Jim Harbaugh clarified the injury situation. Harbaugh said that Morgan's injury wasn't a right ankle fracture, but instead a lower right leg injury involving a broken bone. Matt Maiocco of CSN Bay Area tweets that the injury occurred right above the ankle. Technically, the right ankle fracture diagnosis could still be correct, but Harbaugh apparently wanted to be as vague as possible when describing the injury.
I would guess that Harbaugh is trying to gain a competitive advantage by letting his opponents know as little as possible about the extent of the Morgan injury. That way defenses would have to gameplan for him down the road when Morgan could be ready to return to play.
