Christian Pulisic is a doubt for AC Milan's trip to Torino with a fever, with head coach Massimiliano Allegri insisting he will not be risked if there is a chance he will "infect everyone".
The Rossoneri travel to Turin on Monday with victory potentially taking them back above rivals Inter, who beat Como 4-0 on Saturday, and to the Serie A summit.
However, Milan are likely to be without Pulisic, who also missed last weekend's 1-0 victory over Lazio with a muscular injury.
"Pulisic had a fever last night, we'll see tomorrow whether he's available or not," Allegri told reporters during his pre-match press conference on Sunday.
"We won't take him with us if he's going to infect everyone.
"We hope to have [Santiago] Gimenez back as soon as possible, he's important and we need him numerically and tactically.
"[Zachary] Athekame is working on his recovery. We hope to have [Youssouf] Fofana for Sassuolo [on December 14]. This is a very important week."
Despite Milan's promising position with the midway point in the season approaching, Allegri believes his side are not the "best-equipped" to land their first Scudetto in four years.
"I don't know, it depends on the runs that teams put together," he added. "Inter and Napoli are the best-equipped for the Scudetto, but there are a lot of teams within a few points, which is an anomaly.
"At some stage, the standings will have to stretch out, and we have to stay there.
"We need the conviction to improve. Each one of us has to work to get the most out of it. Nothing is impossible and everything is possible. We have to do our best to achieve whatever is possible."
Torino, meanwhile, occupy 13th place in the Serie A table, with Marco Baroni's side aiming to end a run of five matches without victory.
