The pair could return for the derby with Manchester City on Sunday (4.30pm).
United and City go head-to-head in a huge title clash at Old Trafford.
And Mourinho will need all the help he can get from his squad as they aim to cut the gap to City down to five points.
Paul Pogba is their major absentee due to suspension, and centre-half Eric Bailly is still injured.
But Mourinho has positives ahead of the visit from Pep Guardiola’s team.
“Zlatan is available, Jones is available,” Mourinho confirmed.

Manchester United's likely line-up to face Manchester City at home

“Matic is injured but he plays”
Jose Mourinho
“[Marouane] Fellaini I have to wait until tomorrow, [Michael] Carrick is not available, Bailly is not available.
“[Nemanja] Matic is injured but he plays.”
Jones and Ibrahimovic were not in the squad that beat CSKA Moscow in the Champions League on Tuesday.
But it seems they will feature this weekend.
City boss Guardiola, meanwhile, has said David Silva is now fit to play after being labelled as a doubt earlier this week.
