Things were finally looking up for John Terry. The Chelsea captain was making his return from a four-match ban against Liverpool and had already marked the occasion with a powerful header to put the Blues ahead.
Then, on 35 minutes, Terry found himself backpedaling, with Liverpool's Luis Suarez bearing down on him.
Terry's teammate, Ramires, pushed Suarez from behind, and the result was an awkward collision that left Terry writhing in agony, covering his face as he received treatment.
Everything points towards Terry having suffered a serious knee injury—one that could potentially see him out of action for months.
Gary Cahill coming on - John Terry's immediate reaction suggested he knew right away he had picked up a bad injury there.

Terry had surgery on his right knee in February, and footage appears to show that it's the same one he injured in the clash with Suarez.
The 31-year-old will have a scan on Monday to determine how serious the problem is.
