After returning to action for the Miami Heat in their last two contests against the Sixers, it now sounds like Kyle Lowry could be headed to the sidelines yet again. The former All-Star point guard is now in danger of missing Game 5 after a possible tweak on his hamstring injury in Game 4.

The Heat have officially listed Lowry as questionable ahead of Tuesday's Game 5 showdown against the Sixers (h/t Tim Reynolds of the Associated Press):

Kyle Lowry (hamstring) listed as questionable for Game 5 on Tuesday night.

After missing Game 5 vs. the Atlanta Hawks and Games 1 and 2 against the Sixers, Lowry was finally able to return to action in Game 3. He also played in Game 4 but he definitely did not look like himself for both games. The 36-year-old veteran scored just six points in those two contests, going 3-of-14 from the field and 0-and-8 from distance. Miami lost both games.

It's being reported that Lowry re-injured his hamstring in Game 4, which explains his status for Tuesday's Game 5 matchup.

It's also possible, however, that the Heat are just being cautious here. The questionable tag doesn't necessarily mean that Lowry is going to be out, so at this point, it would be safe to assume that his status is currently up in the air.
