Reece Topley marked his return to first-class cricket after an absence of more than two years by helping promotion-chasing Sussex bowl Derbyshire out cheaply on the opening day of the match at Derby.

The England seamer, whose career has been blighted by back injuries and was making only his sixth championship appearance in just over five years, took 2-23 as Derbyshire were dismissed for 138.

David Wiese led the Sussex attack with 4 for 18 and only Anuj Dal with 35 gave the home side a semblance of respectability.

But Sussex also struggled, losing three cheap wickets, before Stiaan Van Zyl, 49, and Delray Rawlins, 26, carried the visitors to 116-3 at the close.
