Pietrus needs time to strengthen knee

MIAMI -- Celtics coach Doc Rivers said Tuesday morning that newly acquired swingman Mickael Pietrus might need another 10 days to strengthen his right knee before making his debut in green.

Pietrus, who the team announced Tuesday would wear No. 28, had arthroscopic surgery this offseason and that contributed to him failing a physical after being traded to Toronto this offseason. Instead, he facilitated a buyout with the Phoenix Suns, paving the way for him to ink a veteran minimum deal with the Celtics on Saturday.

As the Celtics navigate the start of the season with captain Paul Pierce battling a bruised right heel, a healthy Pietrus would bring welcome depth on the wing (especially with Jeff Green out for the season due to a heart ailment). Instead, Rivers said Pietrus is unlikely to debut until into the new calendar year. Rivers also suggested it might be as much as a month before Pietrus is 100 percent again.
