"A person with knowledge of the prognosis for Josh Smith said the Hawks forward is doubtful to play in Game 3 against the Celtics Friday after he suffered a left knee injury in Game 2 Tuesday.

The person said Smith has patellar tendonitis with inflammation in the injured area but an MRI revealed no structural damage. If Smith misses Game 3 he likely would return for Game 4 Sunday in Boston, according to the person.

The person did not want to be identified because the Hawks have not released the results of Smith's MRI. The Hawks released a statement that said Smith is day-to-day with a "strained left tendon."
