They posted a poor first half showing, having gone behind early on but recovered sufficiently to earn a share of the spoils.
Rovers failed to deal with an early free-kick that was sent to the back-post and Connor O'Riordan bundled in after slipshod defending from the visitors.
Shortly after Rovers were indebted to goalkeeper Ted Sharman-Lowe after a terrific stop to deny Kane Hemmings' close-range header.
The rest of the half saw Grant McCann's men toil to no avail and another couple of smart saves from Sharman-Lowe ensured it was only a 1-0 deficit at the interval.
The second half didn't see a vast improvement and McCann made four substitutions at once, just after the hour mark. And not long after they finally drew level. A Luke Molyneux corner was met by a booming header from Owen Bailey to restore parity.
Crewe had the better of the chances to pinch all the points before Rovers saw a penalty appeal involving sub Joe Sbarra waved away.
Here's how we rated the Rovers players:

Tabiner had him on toast at times. Kept plugging away, mind, and made inroads down the left at important junctures. Photo: Howard Roe/ahpix.com
6. Owen Bailey 6
Some good interceptions but also some sloppy moments. Dropped into defence second half as part of a reshuffle and then provided booming header as he rose to meet Molyneux's set-piece. Photo: Bruce Rollinson/AHPIX LTD
7. George Broadbent 5
Stodgy performance at times with some Hollywood balls that just didn't come off. Persisted and dug in second half, as he kept things ticking over albeit with errors creeping in. Photo: Howard Roe/ahpix.com
8. Harry Clifton 4
First half showing was well under-par, with misplaced passes and a tame volley with the Crewe goalkeeper off his line. Not his day, safe to say Photo: Howard Roe/ahpix.com
