The initial thought was a sprained MCL, suggesting he'd miss a few weeks.
Guice was injured in Washington's preseason opener at New England on Thursday night and could be seen on the sideline with ice on his knee. Previous year at LSU, Guice was hampered by a hyperextended knee, limiting his snaps and forcing him to miss a game. Injuries to Week 1 starter Rob Kelley and prolific third-down back Chris Thompson contributed to that, and Guice was expected to be a major part of solving the problem.
Before his injury, Guice was having a strong training camp, taking snaps with the first unit and displaying the same "violent" running style that he was known for. The team announced the prognosis Friday following an MRI, saying Guice should make a full recovery and be ready to play in 2019.
South Sudan rivals sign final power-sharing deal
The conflict has been fuelled by divisions between the Mr Kiir's Dinka and Mr Machar's Nuer ethnic groups. The South Sudanese President also said that he was "going to sign", the agreement.
Still, Guice's injury continues the streak of bad luck for the organization. Who steps up? It could be Samaje Perine, who had a disappointing rookie season in 2017 but had excellent college production at Oklahoma.
Washington has also had a recent history of their high-profile draft picks not being able to stay healthy. He has two years remaining on his contract.
ESPN's Adam Schefter reported Thursday - the day of the Patriots' preseason opener - that the Patriots will be adding some incentives to Brady's contract in order to likely raise his salary to something more commensurate with other National Football League quarterbacks.
