The fourth official had initially signalled for a minimum of three minutes added time and Pulis was quick to criticise Probert's decision to play over the allotted time.
Tony Pulis: "I thought for an hour we did very, very well. We tired at the end, they had a couple of chances at the end, but I thought we'd really seen it out.
As you can see, the ref's watch was on time
"The disappointing thing is, if you look at the video, we think we should have had a free-kick outside their box with 20 seconds to go.
"Then they (Newcastle) come down and they score, which is over time. First half he (Probert) played a minute and 40 seconds over time.
"And in the second half I think it's 3.40 (into injury time) when they score the goal.
"We need a break, we need one or two things going for us. We missed a great chance at Sunderland last minute and today we've got done in the 48th minute, which was 30 seconds over time."
