Walker (ankle) will not play in Monday's Las Vegas Summer League game, Ira Winderman of the South Florida Sun Sentinel reports. Walker has yet to play this summer, missing every single one of the Heat's Orlando Summer League games as well. Considering these are mostly meaningless outings, the Heat aren't going to take any chances and push Walker to prematurely return. There's a very good chance he's held out of the rest of the summer, which is a tough blow for a player fighting for a roster spot.

Walker (ankle) will not play in Wednesday's Orlando Summer League game, Ira Winderman of the South Florida Sun Sentinel reports. Walker missed Monday's game due to an ankle injury, and he'll sit out again Wednesday. It's likely nothing serious, but the team certainly won't take any chances in an ultimately meaningless summer league contest.

Walker (ankle) is uanvailable for Monday's Orlando Summer League game, Ira Winderman of the South Florida Sun Sentinel reports. Walker should be considered day-to-day moving forward as the Heat are likely just playing it safe by resting him Monday. With approximately three months until the regular season actually begins, this minor ankle issue shouldn't hinder Walker when it matters.

Walker averaged 7.3 points, 1.9 three-pointers, 3.4 rebounds, 1.2 assists, 1.0 steal, and 0.4 blocks in 26 minutes per game during 24 regular season games in 2014-15. Walker spent the last two seasons out of the NBA, playing in the D-League, but a name change (formerly Bill Walker) and some time away earned him a roster spot with the Heat for the second half of the 2014-15 season. He signed two 10-day contracts with the Heat in February and was eventually given a contract for the remainder of the season. Walker saw significant minutes throughout his stint with Miami, earning 13 spot starts. While his comeback was impressive, Walker will be an unrestricted free agent again this summer, and unless he stumbles into a perfect situation, it's unlikely Walker holds consistent standard-league fantasy value next season.

Walker (elbow) is active for Saturday's game against the Raptors, the South Florida Sun Sentinel reports. Walker was listed as out on the initial injury report Saturday, but his sore right knee won't keep him on the sideline. No matter, he's been capped at 21 minutes over the last four games, during which he's averaged two points (on 15 percent shooting), one rebound, one assist, one steal, and 0.8 blocks in 16 minutes.

Walker (knee) won't play Saturday against the Raptors, the Miami Herald reports. Walker is missing his second game in a row, this time due to a sore right knee. Expect James Ennis and Michael Beasley to pick up additional run off the bench Saturday. Meanwhile, consider Walker questionable for Monday's outing against the Magic.

Walker won't play Thursday versus the Bulls, the Palm Beach Post reports. With Walker on the pine, the Heat will rely upon Luol Deng (knee), Udonis Haslem, Michael Beasley (illness), and James Ennis at the forward spots. Until the extent of Walker's injury is known, consider him questionable for Saturday's game against the Raptors.

Walker got the start Sunday, but was held to just two points (1-3 FG, 0-2 3Pt), one assist and two blocks in 19 minutes. Walker started at power forward with Hassan Whiteside (hand) out, and Udonis Haslem sliding over to center. Walker has played at least 17 minutes in each of his past three games but has scored a combined eight points in that stretch and is a combined 2-for-11 from the field.

Walker is starting at power forward against the Pacers on Sunday with Hassan Whiteside (hand) out and Udonis Haslem sliding up to center, the Palm Beach Post reports. Walker has averaged 7.5 points, 3.8 rebounds, 1.5 assists, 1.5 steals, 1.9 three-pointers, and 0.4 blocks in 29 minutes per game through 11 starts this season. He's not great, but his contributions in three-pointers and steals could help someone looking for a desperate streaming option.

Walker was limited to just three points (1-3 FG, 1-2 3Pt), one rebound, one assist, one block and two steals in 17 minutes Tuesday. Walker started with Udonis Haslem (illness) out at power forward. Despite seeing an expanded role, Walker has scored a combined 11 points in his past three games and is shooting 2-for-6 from the floor in his past two. In his 10 previous starts this season, Walker averaged eight points, 4.1 rebounds, 1.5 assists and 1.5 steals.
