Lukas Engel is returning to Middlesbrough this month after a loan spell at FC Cincinnati, but after Real Salt Lake's surprise decision to select the Dane in the MLS Re-Entry Draft, they failed to follow up with an offer that Middlesbrough found acceptable. Engel is currently expected to be reintegrated on Teesside and could be a useful option amid a defensive injury crisis, although a potential departure from the club would not be a huge surprise.
