Dwane Casey wasn't quite ready to show his hand. The Raptors head coach who hinted at lineup changes following an ugly loss in Dallas once again admitted those could still come by Saturday's game against Philly at the Air Canada Centre. But like a poker player who doesn't want to provide any information to his opponents, Casey advised a group of media after practice that they would have to wait and see what game day brought. What Casey did reveal after the formal part of his post-practice scrum broke up was that Landry Fields, a guy many had pegged to be looking at a possible demotion to the second unit, left the Air Canada Centre to have his right hand examined. Seems the hand has been bothering Fields for a couple of weeks now. Casey said he would undergo "precautionary" testing which will tell the Raptors if it's anything structural. While an injury of any sort is never good news for a team, a problem with his hand would explain some of the unbelievable misses the former Knicks forward has had lately. On Tuesday night in Oklahoma City, Fields came under the basket and out the other side clear of defenders but could not convert a basic lay-in. In Dallas, Jose Calderon hit him on the run with a pass a step from the backboard. All Fields had to do was kiss it off the glass but he failed to take the pass cleanly and never did get a shot off. At this point it's only speculation that a move involving Fields was in the offing but with the hand issue now out there, Casey has more justification to pull the trigger.
