Derek Fisher's knee injury is not considered to be serious, but he will have an MRI on Wednesday. Fisher was walking after the game, and Rick Carlisle said that it "doesn't look like a serious situation." The initial belief is that Fisher has a "strained or sprained patellar tendon," but the MRI will provide the full picture. Darren Collison's fantasy stock just went up.

Derek Fisher left Tuesday's game against the Sixers with an apparent right knee injury and went to the locker room. The training staff will check on him and one would think that his 38-year-old frame might not be coming back to the game. Fisher was a game-time decision with the flu, so he's having a tough day. Darren Collison would pick up most of the minutes at point guard.

Derek Fisher will start against the Sixers for Tuesday night's game. Fisher is dealing with an illness and it's unclear how many minutes he can play. The 38-year-old guard has played 30 minutes per game in his last five contests. Darren Collison will continue to come off the bench.

Updating a previous report, Derek Fisher (flu) hasn't ruled himself out yet for Tuesday's game. If Fisher can't go, Darren Collison will start, and with Fisher clearly not feeling well, Collison should be in line for heavy minutes tonight, either way.

Derek Fisher (flu) is out and Elton Brand (groin) is a game-time decision for the Mavericks against the Sixers. Fisher missed shootaround and Darren Collison will start in his place, while groin injuries are always tricky. We should have an answer on Brand soon.

The Mavericks fell in OT on Saturday despite a season-high 20 points from Derek Fisher, who made 5-of-8 FGs (with three 3-pointers) and 7-of-7 FTs in 29 minutes. Fish added four assists and two steals, but he also turned the ball over five times and we may not see another 20-point game from him all season. He's worth a look for low-end value in 14-team leagues, but that's about it.

Derek Fisher played 36 minutes in another start at point guard on Wednesday and had 10 points, three rebounds, four assists, one steal, two blocks and two 3-pointers against Boston. The 36 minutes were a season high for Fisher and Rick Carlisle seems to trust Fisher because he has been playing him in the clutch. Still, it's tough to own him in standard leagues with his limited upside.

Derek Fisher scored 11 points on 3-of-6 shooting (including a three) with two rebounds and six assists in the Mavs' 119-96 blowout win over the Kings on Monday. Fisher consistently took Aaron Brooks to school, and in general owners should keep this outing in perspective against a Kings team that gave up early in the second quarter tonight. O.J. Mayo had 19 points on 6-of-9 shooting (including three treys) with seven rebounds, four assists, and a steal in the win.

Derek Fisher scored seven points and handed out five assists in a win vs. Houston on Saturday, improving his record with the Mavericks to 3-1. Fisher played just under 30 minutes, a barrier he has yet to crack, and he struggled again with his shot at 1-the-5 from the field. Even with a starting job in hand, there's not a lot of upside for Fish in fantasy leagues.

Derek Fisher scored 15 points on 5-of-11 shooting (including three treys) with one rebound and two assists in 27 minutes on Wednesday against the Clippers. This is Fisher's ceiling and it's noteworthy that Darren Collison (18 minutes, five turnovers) was awful tonight. In a deep league Fisher could be worth a look for his 3-point shooting, but expectations should be held firmly in check.
