West Ham youngsters Reece Burke and Josh Cullen have joined Bolton on five-month loan deals.
The pair both have big futures ahead of them, but Hammers boss Slaven Bilic has decided to let the duo leave to gain regular first team football.
Burke, who has 12 senior Hammers appearances under his belt, has spent the previous two seasons on loan - at Bradford and Wigan, respectively.
Cullen, meanwhile, has four Hammers appearances to his name and has spent his previous two seasons on loan at Bradford.
