When the Boston Celtics face the Phoenix Suns on Sunday, Kevin Garnett will not be the only big man out of the game. Suns power forward Amar’e Stoudemire underwent successful eye surgery today and could miss eight weeks, according to multiple reports. Stoudemire suffered a partially detached retina in Wednesday’s game against the Los Angeles Clippers. ESPN has reported Garnett will return to Boston today for an MRI after straining his right knee during Thursday’s loss to the Utah Jazz.
