The Cavs will have a new shooting guard for Tuesday's game against the Boston Celtics, but coach Byron Scott isn't sure yet who it will be.

Anthony Parker's stiff lower back will keep him out of the game and Daniel Gibson was left behind in Boston for more tests on his stiff neck. Scott already ruled out both players for Tuesday's rematch against the Celtics.

The Cavs' options at shooting guard are limited. Mychel Thompson played the entire fourth quarter Sunday night and played well, so he'd have to be considered as a candidate. So, too, is Alonzo Gee, who is more of a small forward, but has played some shooting guard this season.

The Canton Charge are completing a road trip tonight in California and could recall Luke Harangody to help at forward (moving Gee to shooting guard) or they could find a way to bring back Manny Harris, but that would take some manuevering. Harris is not on the Cavs' 15-man roster, meaning someone else would have to be waived. Harris as named the D-League Player of the Week today after averaging 25 points and 7.3 rebounds in three games last week.

The Cavs organization loves the way Harris has put in the work in Canton and didn't pout or feel like he was cheated out of the NBA after a fluke accident at Nike helped cost him a roster spot. He has played well of late and is starting to attract attention around the league, but the Cavs may not have a place for him right now.

The problems at shooting guard will only put more pressure on Kyrie Irving, who has dazzled in the fourth quarter of the last two games. Irving is the third-youngest player in the NBA to make a game-winner since the 2002-03 season, according to STATS, LLC, which defines a game winner as a free throw or field goal to win a game within the last three seconds.

Since he only played 11 games at Duke, Irving didn't have any game winners there, but he said he had a few in high school.

"It's much sweeter, especially at this level," he said. "It's a dream come true for me, first time in Boston Garden playing against the Celtics. I've been watching them for so long and to hit a big shot like that feels good, but now it's time to move on and get ready for Boston tomorrow."
