Jazz center Al Jefferson (25) is brought off the court after going down with a back injury during the second half of the NBA basketball game between the Utah Jazz and the Orlando Magic at Energy Solutions Arena, Wednesday, Dec. 5, 2012.

SALT LAKE CITY — Health issues continue to be a concern for the Utah Jazz.

The team could be without three key players when they take on the Toronto Raptors at 7 p.m. in The EnergySolutions Arena.

Center Al Jefferson (back spasms) and Derrick Favors (strained right arch) both went through shootaround but are game-time decisions due to their injuries.

But the Jazz might also be without starting point guard Mo Williams, who did not attend this morning's workout session while dealing with "gastric distress." Like the bigs, Williams is also a game-time decision.

"We're not for sure what's going to happen," Jazz forward Paul Millsap said.

Jefferson left shootaround early to go to a doctor's visit. The 6-foot-10 center was walking much better than after tweaking his back near the end of Wednesday's 87-81 win over the Orlando Magic.

Jefferson was in a hurry and couldn’t speak to media, but he offered this parting phrase: "I could run 10 miles ... with you on my back."

"Al just comes in and looks like Al. You're not going to know if he's hurt or anything," Millsap said. "He's just going to come in and try to do his job."

Favors went through a light practice Thursday and made it through shootaround without being bothered by his plantar fasciitis. He iced his foot just in case, but his status remains up in the air tonight.

"The last couple of days it's feeling a lot better," the 6-10 forward said. "I'll just go out there and see how it feels during pregame warm-ups. If it feels good, I'll go. If it still feels a little sore, I'll just sit out."

Favors said his foot issue bothers him most when he pushes off or jumps.

"It takes a lot of explosiveness out of my game," he said.

The third-year pro isn't worried about the injury lingering and causing long-term problems.

"As long as I take care of it (with) treatment, do the right things, I'm not too concerned about it," Favors said. "I'm not going to push it. I'm just going out there and see how I feel. If it doesn't feel right, I'm going to sit out."

The Jazz (10-10) outlasted the Raptors (4-15) in triple overtime, 140-133, last month in Toronto. Explosive guard Kyle Lowry, however, did not play in that one.

"They're a really good team," Jazz center Enes Kanter said.

Kanter could possibly start tonight if Jefferson and Favors are out. Jamaal Tinsley started the last times Mo Williams couldn't play, although Earl Watson has replaced him as backup point guard in recent outings.

Jazz coach Tyrone Corbin does not speak to media after shootaround of home games, so it wasn't possible to get insight from him on lineup scenarios.

"I hope they come back because they are great players and they are really important for our team," Kanter said of his ailing teammates. "But if they don't come back, I'm going to go out there and just fight for my team."
