Sleeping on side in the crib

So I put my 3 month old to bed in just his crib tonight and in a matter of seconds he rolls to his side. I moved him back to his back, but now I’m terrified he’s going to roll back over while I’m sleeping and suffocate. Is this okay for him to do? Should I put him back in the bassinet?
