BOSTON (CBS) – Still in need of another guard, the Boston Celtics have expressed interest in seven-year-veteran Carlos Delfino, according to A. Sherrod Blakely of CSNEE.com.

Delfino, who will turn 30 next month, has spent the last three seasons in Milwaukee, and could play both shooting guard of the small forward position. He also played one season for the Toronto Raptors after spending the first three years of his career with the Detroit Pistons.

The 6-6 Delfino averaged nine points and 3.9 rebounds in 2012, starting all but one game for the Bucks.

But the problem the Celtics will continue to run into this offseason is money. They only have the bi-annual exception to offer players — worth about $1.9 million — and it’s unclear if Delfino, who made $3.5 million in 2012, would take such a big pay cut.

Blakely is also reporting Mickael Pietrus remains a candidate to return to Boston. Pietrus played in 42 games for the Celtics last season, contributing off the bench as a three-point shooter and defender. He saw his role increase during the postseason when Avery Bradley went down with a shoulder injury.

Pietrus struggled for stretches but was never really 100-percent for the Celtics. Just as he was starting to play well in late March, he suffered a concussion that sidelined him for over two weeks. Pietrus averaged just 3.5 points in the playoffs on 33-percent shooting from the floor.

But Pietrus has said many times he enjoyed playing in Boston, and was a good locker room guy with his loose attitude. Bringing the Frenchman back would make sense, as he’s had a season to get acquainted with and understand the Celtics defensive system.
