The 22-year-old appeared to suffer a hip injury minutes before half-time after Abraham fell awkwardly having challenged for an aerial ball in the Champions League clash.
Abraham appeared to be in a lot of pain in the hip area as the England international made his way off the pitch at The Mestalla ahead of the half-time break.
The Chelsea FC striker has been in prolific form for the west London side in the Premier League this season under Lampard.
Abraham has scored 10 times and has made two assists in 13 games in the Premier League to fire the Europa League holders into the top-four spots.
Speaking to BT Sport following Abraham’s suspected hip injury, Lampard was optimistic that the Blues centre-forward hadn’t suffered a serious problem.
“It was a bang on the hip, it might not be as severe as we first thought,” Cole told BT Sport.
“I am not sure [how serious it is], he is in the dressing room now so that’s a positive.”
Valencia star Carlos Soler broke the deadlock in the 40th minute before Mateo Kovacic levelled less than a minute later with his first goal for the Blues.
Chelsea FC were 2-1 ahead when Christian Pulisic continued his prolific form before Valencia wing-back Daniel Wass rescued a point for the hosts with eight minutes to go.
