Timberwolves president of basketball operations David Kahn confirmed that guard Brandon Roy began an undisclosed treatment on his right knee "last weekend," but Kahn said no timetable has been determined for his possible return to the lineup. "We'll see what the effects are over the next couple of weeks," Kahn, traveling with the Wolves on the two-game road trip, said of Roy before the team's game Thursday night, Jan. 3, in Denver. "He's been practicing and working out. We're keeping our fingers crossed." Roy had a setback with his knee after he resumed practicing with the team two weeks ago. He said he wanted to seek another form of treatment to help him fully recover from arthroscopic surgery on Nov. 19. Roy has not played since the first half of the Wolves' Nov. 9 game against Indiana at Target Center. Kahn indicated that Roy's situation, even if it improves, will not stop the team from looking at possible trades to add another shooting guard or small forward. Kahn also said the addition of guard-forward Lazar Hayward, signed as a free agent Monday, will have no effect on trade talks. "We've been hit really hard at our wing depth," Kahn said. "As I said last weekend, if we see a move that can benefit our team, we'll make it." Kahn said he didn't anticipate any moves until the NBA trading deadline nears. The deadline is Feb. 21. It's very hard to do a trade in January," Kahn said. "We're in a deadline-driven league."
