Charlotte, which hasn't won since beating Golden State back on January 14, continued to struggle on Wednesday, as they dropped a 102-90 decision to the Minnesota Timberwolves.
"Some nights it's embarrassing, especially when we lose by a lot," Walker said. "No one likes to lose by that many points."
D.J. Augustin returned from a toe injury, playing for the first time in 12 games, but only managed nine points and four turnovers in 24 minutes. The team is still without Gerald Henderson, as he continues to nurse a strained right hamstring.
Charlotte, which is a miserable 1-15 away from home this season, is still 10 losses away from the Cleveland's NBA-record 26-game drought from last season.
Toronto, meanwhile, enters tonight's tilt having lost three in a row after a 113-106 setback to the San Antonio Spurs on Wednesday.
Toronto's bench also chipped in 45 points in the loss.
"Our bench did a great job," coach Dwane Casey said. "Everyone that came in competed and played hard. Now, we have to find a closing group to close the game. And it goes back to being healthy."
Injuries have been a problem for the Raptors, who continue to play without leading scorer Andrea Bargnani. He has missed 18 of his last 20 because of a strained calf and will likely sit tonight. Also, Jerryd Bayless (ankle) and Linas Kleiza (knee) are questionable for tonight's affair.
Charlotte swept its four-game season series with the Raptors last season and has won four of its last six in Toronto.
