David Lucas, who will be released by Northamptonshire at the end of the season, is set to join Worcestershire on a three-year deal.
Worcestershire made a formal 28-day approach for Lucas before Northamptonshire took the decision not to renew his contract and are close to securing his services.
Lucas has already played for three counties having started with his native Nottinghamshire before moving on to Yorkshire for a season in 2005.
His county career appeared to be over when Yorkshire released him but a successful stint playing Minor Counties cricket for Cambridgeshire in 2006 persuaded Northamptonshire to give him another go.
Worcestershire have found extra money for director of cricket Steve Rhodes’s cricket budget for next season and are seeking reinforcements for their seam bowling attack as Jack Shantry, left out of the current County Championship match against Blackpool, Richard Jones and Chris Russell have not progressed this season.
Worcestershire have already released former Middlesex seamer Chris Whelan after two injury-ravaged seasons and have given opportunities to former Wiltshire seamer Nick Harrison in their last two Clydesdale Bank 40 matches.
Harrison, who had trials with Durham two years ago, has impressed in second team cricket this season and appears to have edged ahead of Russell in the pecking order at New Road.
