Try dumbbell bench pressing, this way you don’t lock your shoulders out.

Having had a torn rotary cuff and type 2 slap tear my days of bench pressing are pretty much over. Having said that with my dumbbell bench press I’m able to lift moderate weigh but focus mainly on higher reps and squeezing, so far I would say my gains are better than ever.

One thing I will say if your shoulder is causing you pain let it rest, using ice, ibuprofen and light exercises. Also some good rotary cuff strength exercises on YouTube which have also helped.
