Crystal Palace will look to pull clear of the relegation zone as they welcome Hull City to Selhurst Park on Tuesday evening.
Palace (6-2-14) have been much-improved since Tony Pulis took over as manager but remain just two points clear of the drop and frustratingly inconsistent. Pulis' side crashed out of the FA Cup at the hands of holders Wigan Athletic on Saturday, but after the game, the Palace manager was more concerned with a head injury to Jonathan Parr than with the result.
"He has gone to hospital for a scan. We need to look at the incident again, but it looks like the lad has caught him. It will be interesting to see it again on from a different camera angle.
"We think it was caused by the impact and we are not sure whether it is a problem with his jaw or neck but we will know more when the results of the scans are with us. The referee was not far away from the incident as he wasn't when he made the call for the penalty towards the end of the match but on the day that call didn't go our way."
Hull (6-5-11) have lost three straight league games since hammering Fulham 6-0 over Christmas, but beat Southend United - managed by former Tigers boss Phil Brown - to reach the round of 16 in the FA Cup at the weekend.
"We have to stay in the Premier League, that is where we all want to be. However, there is no harm in a cup run because sometimes it can galvanise you and I am delighted we have got through," said manager Steve Bruce. "Wigan proved to everybody last year, that while a club like us cannot win the Premier League - we understand that, we are not good enough - but we can win the FA Cup because you just never know the draw, the big teams could draw each other.
"We did not bring in six or seven youngsters, we have brought in guys with bags of experience, some who are international footballers. It is great for us that we can change the team and still be strong enough to get through."
Crystal Palace have injury doubts over Parr (neck), Kagisho Dikgacoi (calf), Jerome Thomas (calf) and Jack Hunt (ankle), while Hull have concerns over the fitness of James Chester (hamstring) and Sone Aluko (calf).
Hull have won just once away from home all season and a league-low seven road goals.
Fourteen of Palace's 20 league points have been picked up at home, but they have scored a league-worst nine goals in 11 games on their own patch.
A Barry Bannan goal helped Palace to a 1-0 win when these teams met at the KC Stadium earlier in the season, and the Londoners are unbeaten in their last seven meetings between the clubs.
