"The Denver Nuggets' injury list might have grown during Friday's practice when reserve guard Raymond Felton was said to have twisted an ankle.

The severity of the injury was not known. Felton did not meet with reporters afterward.

The Nuggets continue to limp their way into the opening round of the playoffs against the Oklahoma City Thunder. The best-of-seven series begins Sunday at 8:30 p.m. inside Oklahoma City Arena.

Depending on his status, Felton could join a healthy list of unhealthy teammates:

* Starting point guard Ty Lawson sprained his left ankle in Wednesday's regular-season finale and did not practice Friday, but said he expects to start Game 1.

* Starting guard Arron Afflalo continues to recover from a nagging hamstring injury that saw him miss 13 of the last 18 games. Afflalo said he intends to play in the series, even if he's not 100 percent."
