Pakistan left-arm seamer Junaid Khan will return to Lancashire this season as an overseas limited-overs signing.
The 24-year-old, who helped the county to Twenty20 finals day in 2011, will join in time for their opening T20 Blast match against Nottinghamshire Outlaws on 16 May.
"Junaid had a period with us previously and was extremely successful," said cricket director Mike Watkinson.
"He turned in some great performances and was very effective for us."
Worcestershire had also been after Junaid for T20, before the county eventually signed New Zealand's Colin Munro.
Watkinson said Junaid's left-arm pace would bring "something different", just as it had done last season when New Zealand international Mitchell McClenaghan was part of the squad.
"Junaid has matured as an international cricketer of note," added Watkinson in at interview with BBC Radio Lancashire. "He's had interest from other counties, but his heart is with us."
