With Henry Tuilagi getting a run-out for the development team in midweek and Martin Castrogiovanni working his way back from an injury suffered in the early stages of the RBS Six Nations, Howard has almost his whole squad in contention.
"Castro has a chance of being involved this weekend," Tigers head coach Howard said. "The medical team and physios have done a fantastic job and put in a great amount of effort to get him ready.
"We will possibly be going into the weekend without only Scott Bemand and Ollie Smith due to injury and if that is the case then we are doing really well."
Tuilagi joined Ian Humphreys, Jordan Crane and James Hamilton in the Guinness A League victory at Newcastle on Monday evening to push their claims for this weekend's European showdown and Howard also confirmed that lock Leo Cullen would be in contention after overcoming a foot injury. Prop Julian White is another possible inclusion against Stade Francais after sitting out the EDF Energy Cup semi-final victory over Sale Sharks last weekend.
"We had some guys missing last week but the others stepped up very well," said Howard. "I was particularly happy for Michael Holford, it was a big day for him playing directly against Andrew Sheridan."
Skipper Martin Corry sat out the second half of the win over Sale with an arm injury, but Howard is hopeful of being able to include him on Sunday.
"Martin has a real chance. We are going to give him all the way up until we have to announce the side on Friday," he said. "There is no structural damage, just inflammation, and if that goes down then he will be all right to play."
