Following his outing at Daytona last month with United Autosports, Paul di Resta will rejoin Zak Brown and Richard Dean's squad in the next two rounds of the IMSA series.
The former F1 driver and DTM champion, who finished fourth in the Rolex 24, will race alongside Bruno Senna and Phil Hanson at the Sebring 12 Hours and at the Six Hours of Watkins Glen onboard the team's Ligier JS P217.
"I’m massively excited to be taking on some more races in IMSA," said di Resta.
"After the success we had in Daytona and what could have been, I’ve really got the bug for doing more and why not be part of it with United Autosports where it all started.
"It’s a new task for the team racing out in America and there’s lots going on, but being part of that back in the car alongside Bruno and Phil is great.
"There’s plenty of work to do and I’m looking forward to undertaking these two races and seeing what it leads to.
"Hopefully we can have a great result and the team can work together to get the best out of it."
Co-team owner Zak Brown is equally happy to welcome back the Scot.
"It’s great to have Paul back with the team for Sebring and Watkins Glen," said the McLaren boss.
"He did a fantastic job at Daytona and really settled into sports car racing so to have him racing alongside Bruno and Phil will only strengthen our campaign out in America."
