Knicks' Joakim Noah: Doubtful for Tuesday

Noah (illness) has been downgraded to doubtful for Tuesday's game against the Trail Blazers, Ian Begley of ESPN.com reports.

Analysis:

After failing to practice Monday, the Knicks had initially listed Noah as questionable for Tuesday, but the decision to bump his down to doubtful suggests he's at serious risk of missing his second straight game. It looks likely that Kyle O'Quinn will pick up another start at center, though he may end up splitting the minutes at the position with Willy Hernangomez.
