On the same day that one back court player returned from injury, another went down. The Rockets got a bit of good news this morning when it was announced that James Harden returned to practice, but much of the optimism associated with that returned waned when it was also reported that Jeremy Lin had to leave practice early with a rolled ankle. Harden, as you might remember, played on a sprained ankle on Saturday night against the Mavericks, scoring 39 points in a losing effort, but was unable to participate in the team shootaround yesterday morning and missed the Monday night contest against the Spurs. As I wrote last night, despite the minor nature of Harden's injury, ankle injuries are always a concern because they have a tendency to relapse and can limit a player's mobility long after he returns to the floor.
