Draw dents Preston and Coventry's play-off hopesCoventry City's three-game winning run came to an end in a goalless draw at Preston North End that did little to strengthen either side's hopes of reaching the Championship play-offs.
The in-form visitors went closest when Freddie Woodman parried Callum Doyle's fierce long-range strike behind and Jamie Allen shot narrowly over.
Preston did not produce an effort on target in the first half as their unbeaten streak extended to four games with a draw that left the hosts seven points shy of the top six.
Brad Potts sent a volley high and wide and Ched Evans sliced his finish out of play after breaking free in front of goal as Preston failed to score for a third time in five matches.
On-loan Manchester City forward Liam Delap could not capitalise on an excellent opportunity when the 20-year-old shot wide after being introduced as a substitute.
Coventry goalkeeper Ben Wilson also palmed away Daniel Johnson's curling second-half attempt to prevent the midfielder from scoring his second goal in four days following North End's 2-1 win at home to Wigan Athletic on Saturday.
The Sky Blues have now not won in 21 league visits to Deepdale since 1949, with North End unbeaten in 19 editions of the fixture.
Mark Robins' side, who visit Huddersfield Town on Saturday, moved a point above West Bromwich Albion into 10th, five points behind sixth-placed Luton Town.
North End remained 12th before their trip to Watford on the same day, two points above Bristol City and Reading.
Coventry boss Mark Robins told BBC CWR:
"It had 0-0 written all over it - there was no real control over the game. We had some decent patterns at times but nothing consistent. Ben [Wilson] had very little to do and their goalkeeper was worked.
"We fashioned a couple of half-chances. Jamie Allen went through in the first half and really should have scored, then we lost him at half-time to an injury and he'll be out for a while. The reality of it is, we just haven't got the depth of players. There's no chance.
"Fatigue is a big thing. It feels flat because you're looking at trying to kick on and it's very difficult, which has been the way throughout my tenure. It's a point gained, really - we've not got anything here for a long time."
